This invention relates to devices for locking'a pair of cylindricalmembers together in a manner to permit of their ready removal, theinvention being primarily designed for detachably securing the bottom ina bucketof the character disclosed in my Patent #1.,523,604, grantedJanuary 20, 1925, although the invention is adapted for other uses.

Specifically, the invention aims to provide means for preventingrelative rotation between inner and outer cylindrical members which areincluded in the bucket structure,

and where one of'said members carries a lug or lugs engageable withincircumferential notches provided in the other member.

With the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

In the drawings Figure 1 is an elevation illustrating the invention inlocked position.

Figure 2 is a fragmentary elevation with thelocking means released.

Figure 3 is a section on the line 33 of Figure 1.

Figure 4 is an enlarged fragmentary section on the line 4 4 of Figure 1.

Referring to the drawings in detail wherein like characters of referencedenote corresponding parts, the reference character 10 indicates ahollow cylindrica'lmemberwhich may form a part of a bucket of thecharacter 2 shown and described in my patent above mentioned. The bucketis provided with a bottom 11 and the latter carries a sleeve 12 which isprovided with circumferentially spaced longitudinally disposed slots 13which are open at one end and with which communicate notches 14, thelatter being disposed. circumferentially of the member 10. The innercylindrical member or sleeve 12 is provided with radially extendingcircumferentially spaced lugs 15 which are adapted to be inserted in theslots 13 as shown in Figure 2 and moved'into the notches 14 as shown inFigure 1.

. In order to prevent accidental removal of the lugs from the notchesand consequently separation of the cylindrical members, there isprovided a locking bar 16. This bar is provided along its opposite edgeswith tongues 17 which operate in grooves 18 pro vided in the opposedwalls of one of the slots 13 This bar is adapted to be arranged acrossthe end of one of the notches 14 as shown in Figure 1 of the drawingsand will act to prevent the lug 15 from leaving the notch. As relativerotation of the inner and outer cylindrical members is thus prevented,the other lugs 15 will be held within their respective notches.

Housed within a bore 19 provided in the Wall of the outer cylindricalmember 10 is a dog 20. This dog is yieldingly forced outward by means ofa spring 21 and its outer end is beveled to engage the walls of V-shaped notches 22 provided along one edge of the bar 16. WVhen the dogis engaged in the uppermost notch 22 as shown in Figure 1 of thedrawings, the lug 15 will be locked within its notch. In order torelease the lug and permit of separation of the inner and outercylindrical members, the bar 16 is moved to the position shown in Figure2 so that the dog 20 engages the lowermost notch 22. In this positionthe inner and outer members may be rotated relative to one another sothat the lug 15 may be disengaged and the members separated.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having described the invention What is claimed is 1. A latch comprisinginner and outer members, said outer member having a slot in the Wallthereof and a notch Communicating With said slot, a lug on said'innermember and adapted to enter said slot and pass into the notch, and alocking bar slidably mounted in said slot and adapted to close the notchWhen in one position for locking the lug.
